The base meter of photoelectric direct reading remote water meter adopts the rotor-wings water meter, the meter head is equipped with a photoelectric direct reading sensor and encapsulated with a plastic sealing structure, the electronic part and the mechanical part of the base meter are not in direct contact, which does not affect the measurement performance of the base meter. The meter reading method is diverse, which is suitable for various water uses in cities and towns.
It adopts photoelectricity counterpoise direct reading technology, with four bit direct reading and each word wheel has at least five groups of luminous tubes and receiving tubes. Combined with the upper computer system, it establishes a remote automatic meter reading management system to realize the automation of meter reading and monitoring.
Material: Brass
Application: Suitable for small industrial and domestic water use.
Technical data conform to international standard ISO 4064.
Accurate measurement (Class B), no pulse cumulative error.
Low-power performance design, battery life up to 8 years, it doesn't need a power supply except when meter reading or valve control is required.
Top Level IP68 water proof.
Using non-contact sensor, the electronic part will not affect the original performance of mechanical water meter.
Compatible with a variety of communication protocols: M-BUS, Lora, NB-IOT or other customer specified protocols.
Ordinary two core wires are connected, regardless of positive and negative polarity, can complete data communication and provide meter power supply at the same time.
Doesn’t need initialization, the meter address can be set flexibly, and the maintenance workload of the meter reading system is small.
Advanced data coding and validation technology are adopted, with high communication reliability.
Fully sealed design, waterproof, damp-proof and anti-attack, no data loss due to power failure or network failure.
